Yes, Dhoni can hit the cricket ball harder than anyone when it is in the slot but Gibbs has the class to hit even short and rising balls over the fence which I rarely see Dhoni do. The 6 sixes that gibbs hit against Netherland was not of full deliveries but of rising balls which he played staight or towards mid-wicket and I that that was fantastic. Dhoni,I feel can hit only if the ball is full or wide and high and in the slot to hit for him.

yes if Dhoni plays in same attacking style as he does now days then he can match with Gibbs.the other big hitter would be Kevin Peterson both Dhoni and kevin Peterson are tremendous hitters of cricket ball.to compare them with Gibbs it will take time as Gibbs is more experienced then Dhoni and Peterson.
